摘要：

Structured windings and steel poles can be used to create a homogeneous field in a volume of interest (VOI) outside of a coil configuration. The methodology is explained and a first application to an optimized open-MRI imager for breast imaging is presented. Similar methods have been used to design a gradient coil set to similarly project uniform gradient into the same VOI. Aspects of the design and cryogenics of the magnet are discussed.
